Silver coins have played a major role in the history of the United States. From early 18th-century coinage to modern bullion coins, US silver coins remain highly valued by collectors, investors, and historians.

This guide explains the types of US silver coins, their silver content, value, and how to identify authentic pieces.

What Are US Silver Coins?

US silver coins are coins minted by the United States that contain a significant percentage of silver in their metal composition.

Most classic US coins minted before 1965 were made with 90% silver and 10% copper. These coins are often called “junk silver” in the bullion market because their value comes primarily from the silver content rather than rarity.

Types of US Silver Coins

1. Silver Dollar Coins

Silver dollars are among the most popular American coins.

Common examples include:

• Morgan Silver Dollar (1878–1921)
• Peace Silver Dollar (1921–1935)
• American Silver Eagle (1986–Present)

These coins typically contain .7734 troy ounces of silver (Morgan and Peace) or 1 troy ounce (Silver Eagle).

2. Silver Half Dollars

Half dollars were also widely produced in silver.

Important varieties include:

• Walking Liberty Half Dollar (1916–1947)
• Franklin Half Dollar (1948–1963)
• Kennedy Half Dollar (1964 – 90% silver)

Kennedy halves minted 1965–1970 contain 40% silver.

3. Silver Quarters

US quarters were made with 90% silver until 1964.

Popular series include:

• Standing Liberty Quarter (1916–1930)
• Washington Quarter (1932–1964)

Each silver quarter contains approximately 0.1808 troy ounces of silver.

4. Silver Dimes

Dimes also contained silver until 1964.

Major series include:

• Mercury Dime (1916–1945)
• Roosevelt Dime (1946–1964)

Each silver dime contains 0.07234 troy ounces of silver.

Why 1964 Is Important

The year 1964 marks the end of 90% silver circulating coins in the United States.

Due to rising silver prices and metal shortages, the US government switched to copper-nickel clad coins starting in 1965.

This makes pre-1965 coins highly sought after by investors and collectors.

Silver Content in Common US Coins

Coin	Silver Content	Silver Purity
Silver Dime	0.07234 oz	90%
Silver Quarter	0.1808 oz	90%
Silver Half Dollar (1964)	0.3617 oz	90%
Morgan/Peace Dollar	0.7734 oz	90%
American Silver Eagle	1 oz	99.9%

 

How to Identify US Silver Coins

You can quickly identify silver coins using these methods:

1. Check the Date

Coins dated 1964 or earlier are usually silver.

2. Look at the Edge

Silver coins do not show a copper stripe on the edge.

3. Weight Test

Silver coins weigh slightly more than modern clad coins.

4. Magnet Test

Silver is not magnetic, so it will not stick to a magnet.

Are US Silver Coins a Good Investment?

Many investors buy US silver coins because they offer:

• Intrinsic silver value
• Historical significance
• Strong liquidity
• Protection against inflation

Coins like the American Silver Eagle are especially popular for precious metal investment.

Most Valuable US Silver Coins

Some coins are extremely valuable due to rarity.

Examples include:

• 1893-S Morgan Silver Dollar
• 1916-D Mercury Dime
• 1901-S Barber Quarter

Rare specimens can sell for thousands or even millions of dollars at auctions.

Where to Buy US Silver Coins

• Coin dealers

• Auctions
• Online bullion marketplaces

Always verify authenticity and purchase from reputable sellers.
